IMPROVEMENT IN :BUTTER-MACHINE.

The Schedule referred 'co in these Letters Patent and'making part'of the same.

To all whom it 'may concern Be it known that LDAvENPoRT Rocnns, of Mount Gilead, in the county of Morrow, and State of Ohio, -have invented a new and improved Butter-Machine.; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable -others skilled inthe ait to make and use the same, reference 'being had to the accompanying drawings, forming part of this specification, in which- Figure 1 represents a vertical longitudinal section oi' my improved butter-machine.-

Figure 2 is afplan or top view, partly in section, of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new machine for agitating` butter, after the lsame hasrbeen vproduced in a churn.

The invention consists in a novel arrangement of a conical vessel containing a revolving-toothed cone, with bevelled teeth, wheeby'the butter is graduallycalried from one end'of the vessel to the other, and thoroughly' cut up and agitated during the passage.

A, in the drawing, represents a frame, of suitable sizeand shape, supporting a horizontal conical vessel, B, which is made of wood, or other suitable material', and which has its upper half a made removable, to form a lid.

In the frame are the .bearings of a horizontal shaft, C, which passes lengthwise through the vessel B, as shown, andwhich carries within said vessel a conical block, D.

Upon the block D are fitted, in spiral lines, projecting teeth or pins, b b, which are bevelled toward the smaller end ofthe vessel B, as shown in g. 2.

The lid a has an aperture, c, and a hopper, d, above purposes specified.

it, at the large end, and the lower part of the vessel has an aperture, e, shown by dotted lines in iig. 2, at the small end. A

The butter to be worked is put into the hopper d, and is forced down by a plunger, j', which is suspended from a lever, Ffpivoted'to an upright of the frame A. From the inner side of the vessel B, project teeth g g, which are lso set as to be cleared by the 'teeth b.

regulate the discharge, which is 'different in hot andcold weather.

Having thus describedvmy invention, What i' claim as new, and desire to secure by Let- .ters Patent, is-

1. The combination, with a hollow cylinder, having teeth g, and a revolving shaft, D, having the bevelled teeth l1 spirallyarranged thereon, of the vhopper and power-plunger, all arranged, with respect to each other, substantially as shown and described.v v

2. The improved hollow cylinder B, having removable top a, inlet-hopper el, and outlet-aperture c, all constructed and formed in onepiece, as and for the D. ROGERS. Witnesses J ons RUSSELL,
